Whether your meter uses "E", "ER", or another way of designating an error, we've all run into those days where it seems like we waste a whole vial, drum, or disc of strips (and lancets, if you use the Renew device!) just to get that magical number. By the time you get that "beep", you're certain you're reading fifty points off one way or the other, just due to the stress of getting the bloody lancet to produce a bloody large-enough blood drop that beads up on -- rather than wets -- the surrounding skin, and the bloody strip to take up enough of that blood to produce a bloody glucose reading.
(And yes, "bloody" is meant both as description and expletive.)
